Description

  The present invention relates to a labeled container that can suppress condensation.

2. Description of the Related Art Conventionally, containers with labels in which various labels are attached to containers containing various contents such as beverages for decoration purposes have been widely distributed.
Such labeled containers are often eaten and eaten after being cooled in a refrigerator or the like. However, when the cooled container is taken out of the refrigerator or the like, condensation occurs rapidly on the outer surface of the heat-shrinkable label, which flows down and wets the mounting surface such as the desk or wets the handle.
As a measure for suppressing such wetting, Patent Document 1 discloses that a heat-shrinkable label in which a foamed resin layer is laminated on the inner surface of a film layer is attached to a container. Since such a label has a heat insulating property due to the foamed resin layer, dew condensation on the label surface can be suppressed.
However, even the labeled container of Patent Document 1 cannot sufficiently suppress dew condensation, and further improvement is required.

JP 2001-1254889 A

  The objective of this invention is providing the container with a label which can suppress dew condensation effectively.

  The labeled container of the present invention has a container and a dew condensation suppression label attached to the container, and the dew condensation suppression label has a cellophane layer on the surface thereof.

In a preferred labeled container according to the present invention, the cellophane layer is laminated on the surface of a support film including a film having heat insulating properties.
In a preferred labeled container of the present invention, a small hole penetrating in the thickness direction is formed in the surface of the cellophane layer.
In a preferred labeled container according to the present invention, the dew condensation suppression label is attached to the container in a state where a gap is partially provided between the container and the dew condensation suppression label.

  The container with a label of the present invention is provided with a cellophane layer on the surface of the dew condensation suppression label. Therefore, even if moisture adheres to the surface when it is taken out at room temperature after being cooled in a refrigerator or the like, It is absorbed by the water and does not collect as water droplets on the surface. Such a labeled container can effectively suppress condensation.

[First Embodiment]
1st Embodiment is related with the container with a label by which the dew condensation suppression label formed in a cylinder shape is mounted | worn with the container.
FIG. 1 is a plan view of the dew condensation suppression label of the first embodiment as viewed from the front side, and FIG. 2 is a cross-sectional view of the dew condensation suppression label cut in the lateral direction.
1 and 2, the dew condensation suppression label 1 of the first embodiment includes a label base 4 having a cellophane layer 2 on the surface, and a design printing layer 5 provided on the label base 4.
The dew condensation suppression label 1 is formed by attaching the back surface of the first side end portion 4a of the label base material 4 to the outer surface of an adherend such as a container and winding it around the adherend. It is formed in a cylindrical shape by superimposing the back surface of the second side end portion 4b on the surface of the side end portion 4a and bonding the overlapped surface. That is, the dew condensation suppression label 1 of the present embodiment is a single-sheet label before being attached to the container, but is formed in a cylindrical shape at the same time as being attached to the container.
In addition, the 1st side edge part 4a and the 2nd side edge part 4b of the said label base material 4 are the edge parts extended in the vertical direction of the label base material 4, and the 1st side edge part 4a and the 2nd side edge part The part 4b is an end part facing in the lateral direction. In addition, the said horizontal direction is corresponded to the circumferential direction at the time of mounting | wearing with the said dew condensation suppression label 1 to a to-be-adhered body, and the said vertical direction is a direction orthogonal to the said horizontal direction.

As shown in FIG. 1, the dew condensation suppression label 1 (label base material 4) before being formed into a cylindrical shape is formed in a substantially rectangular shape in plan view.
The label substrate 4 has a support film 3 and a cellophane layer 2 laminated on the surface side of the support film 3.
The support film 3 is provided to support the cellophane layer 2. The support film 3 and the cellophane layer 2 are laminated and bonded via an appropriate adhesive layer 61.
The cellophane layer 2 may be the same shape and size as the support film 3 as shown, or may be smaller than the support film 3 (not shown). When the cellophane layer 2 has a smaller area than the support film 3, the cellophane layer 2 is laminated and bonded to a part of the surface of the support film 3.

  The cellophane layer 2 is usually composed of a cellophane film. The cellophane layer 2 is usually colorless and transparent, but may be colored and transparent. In this specification, transparent (colorless transparent or colored transparent) means that things on the back side can be seen through from the front side, and opaque means that things on the back side cannot be seen through from the front side or things on the back side are discriminated. It means that you cannot see through as much as you can.

  Cellophane film usually obtains slurry-like viscose by reacting fiber obtained from cotton, pulp, etc. with carbon disulfide in the presence of alkali, and neutralizes the viscose with an acid such as sulfuric acid. However, it can be obtained by discharging from a slit to form a film and converting it into cellulose, followed by washing with water, desulfurization, bleaching and the like.

The cellophane layer 2 is not particularly limited as long as it is a cellophane film having no waterproof surface on the surface. Cellophane films that do not have a waterproof surface on the surface include normal cellophane films (cellophane that is not waterproofed on the front and back), normal cellophane films that are colored and transparent, and cellophane that is waterproof on the back. A film etc. are mentioned. As the cellophane film having a waterproof treatment on the back surface, a moisture-proof coating agent containing vinyl chloride resin, vinylidene chloride resin, acrylic resin, urethane resin, fluorine resin, olefin resin, etc. was applied to the back surface. A single-side moisture-proof cellophane film can be used. When using a cellophane film having a waterproof treatment on the back surface, the cellophane film is laminated on the support film 3 with the back surface facing the support film side.
The thickness of the cellophane layer 2 is not particularly limited, but if it is too small, the amount of moisture absorbed is relatively reduced, and therefore it is preferably 10 μm or more, and more preferably 20 μm or more. The thickness of the cellophane layer 2 is preferably as large as possible from the viewpoint of suppressing dew condensation. However, in consideration of material costs and the like, the thickness is preferably 100 μm or less, and more preferably 80 μm or less.

The support film 3 may be transparent (colorless transparent or colored transparent) or opaque. When the design printing layer 5 is provided on the back side of the support film 3, a transparent support film is used.
The support film 3 is not particularly limited, and a synthetic resin film, a foamed resin film, a nonwoven fabric, paper, a synthetic paper, two or more kinds of laminates selected from these, and an arbitrary functional layer such as a light barrier layer are laminated thereon. Can be used.
From the viewpoint of supporting the cellophane layer 2 and further suppressing the dimensional change of the label substrate 4 caused by water absorption of the cellophane layer 2, the support film 3 preferably has some rigidity and mechanical strength. The support film 3 preferably contains a synthetic resin film.
Moreover, it is preferable that the support film 3 contains the film which has heat insulation like a foamed resin film or a nonwoven fabric from a viewpoint of improving a dew condensation suppression effect. Hereinafter, a film having a heat insulating property is referred to as a heat insulating film.
Therefore, any one of (1) using a synthetic resin film, (2) using a heat insulating film, and (3) using a laminate including a synthetic resin film and a heat insulating film is preferable as the support film 3.

The synthetic resin film is not particularly limited, and polyester resins such as polyethylene terephthalate and polylactic acid; olefin resins such as polyethylene, polypropylene and cyclic olefin; styrene resins such as polystyrene and styrene-butadiene copolymer; Examples thereof include a film containing a thermoplastic resin such as a vinyl resin. The synthetic resin film may be a multilayer film in which two or more resin layers are laminated. The synthetic resin film may be either transparent or opaque. The thickness of the synthetic resin film is not particularly limited, and is, for example, 9 μm to 100 μm.
The foamed resin film is not particularly limited, and examples thereof include a polyester resin such as polyethylene terephthalate; an olefin resin such as polyethylene and polypropylene; a styrene resin such as polystyrene; and a foamed resin film mainly composed of a polyurethane resin. Is mentioned. The expansion ratio of the foamed resin film is preferably about 5 to 20 times. Examples of the foamed resin film include those having a thickness of about 0.3 mm to 1.0 mm and an expansion ratio of about 3 to 40 times.

The nonwoven fabric is not particularly limited, and synthetic fibers or semi-synthetic fibers such as polyester, polypropylene, polyethylene, rayon, nylon, cupra, cellulose, or natural fibers are bonded to each other by an adhesion method, a needle punch method, a spunbond method, a melt blown method, or the like. A non-woven fabric produced in a sheet form by a method, a Japanese paper-like non-woven fabric produced from a pulp fiber or the like by a paper-making method, or the like can be used. As the fibers constituting the nonwoven fabric, solid fibers, hollow fibers, or mixed fibers thereof can be used, and it is preferable to use hollow fibers or mixed fibers thereof because they are more excellent in heat insulation. The thickness of the fiber is preferably about 2 to 5 denier. Basis weight of the nonwoven fabric is not particularly limited, for ^example, those of about ^{10g / m 2 ~50g / m 2} .

FIG. 2 shows a layer structure when the synthetic resin film 31 of the above (1) is used as the support film 3.
FIG. 3 shows a layer structure when the heat insulating film 32 of (2) above is used as the support film 3. In this case, a heat insulating film 32 (such as a foamed resin film or a non-woven fabric) is laminated on the back surface of the cellophane layer 2. In the case where the support film 3 is constituted by such a heat insulating film 32 alone, it is preferable to use a foamed resin film from the viewpoint of mechanical strength. On the other hand, it is usually preferable to use a non-woven fabric from the viewpoint of a nonwoven fabric that is an aggregate of fibers having better water absorption than a foamed resin film and retaining more water absorbed by the cellophane layer 2. It is more preferable to use a nonwoven fabric composed of hydrophilic fibers such as cellulose fibers and natural fibers such as cotton and / or synthetic fibers subjected to a hydrophilized surface treatment.

4 to 7 show a layer structure in the case where a laminated body including the synthetic resin film 31 and the heat insulating film 32 of (3) above is used as the support film 3. 3 to 7 are cross-sectional views of the dew condensation suppression label 1 of each modification taken along the same line as the line II-II in FIG. 1 (plan views of the dew condensation suppression label 1 of each modification are shown in FIG. It is omitted because it is the same as 1).
When using a laminated body like FIG. 4 thru | or FIG. 7, the synthetic resin film 31 and the heat insulation film 32 (a foamed resin film, a nonwoven fabric, etc.) are adhere | attached through the contact bonding layer 62. FIG. Since the synthetic resin film 31 imparts mechanical strength to the support film 3, when the nonwoven fabric is used as the heat insulating film 32, it is preferable to configure the support film 3 with a laminate. But as the support film 3, you may use the laminated body of a synthetic resin film and a foamed resin film, and the laminated body of a synthetic resin film, a foamed resin film, and a nonwoven fabric.

In the support film 3 shown in FIG. 4, a heat insulating film 32 is laminated and bonded to the surface side of the synthetic resin film 31. In this case, the heat insulating film 32 is laminated on the back surface of the cellophane layer 2. As described above, the non-woven fabric is excellent in water absorption in the heat insulating film 32, and can retain more water from the cellophane layer 2, so that the heat insulating film 32 laminated on the back surface of the cellophane layer 2 as shown in FIG. Is preferably a nonwoven fabric.
In the support film 3 shown in FIG. 5, a heat insulating film 32 is laminated and bonded to the back side of the synthetic resin film 31. In this case, the synthetic resin film 31 is laminated on the back surface of the cellophane layer 2.
In the support film 3 shown in FIG. 6, heat insulating films 32 are laminated and bonded to the front surface side and the back surface side of the synthetic resin film 31, respectively. In this case, the heat insulating film 32 is laminated on the back surface of the cellophane layer 2. Also in this case, it is preferable that the heat insulation film 32 laminated | stacked on the back surface of the cellophane layer 2 is a nonwoven fabric for the same reason as the above-mentioned. 6 may be a nonwoven fabric, a foamed resin film, or the like.

2 to 6, the cellophane layer 2 is laminated and bonded to the support film 3 through an adhesive layer 61.
The adhesive constituting each of the adhesive layers 61 and 62 is not particularly limited as long as it can appropriately bond the two layers, and a conventionally known adhesive for dry laminating or the like can be used. Each of the adhesive layers 61 and 62 may be transparent (colorless transparent or colored transparent) or opaque. When the design print layer 5 is provided on the back side of the adhesive layers 61 and 62, a transparent adhesive layer is used.

In addition, each of the adhesive layers 61 and 62 in the illustrated example is provided in a solid shape.
That the adhesive layer is provided in a solid form means that the adhesive continuously extends in the surface direction and the adhesive is provided in one layer. In addition, each of the adhesive layers 61 and 62 may be independently provided in a non-solid shape. The adhesive layer 61 is provided in a non-solid form, and the adhesive does not form one layer in the surface direction, and the adhesive is scattered innumerably in the surface direction without the adhesive. It means being provided. Examples of the non-solid adhesive layer include a case where the adhesive is provided in a collection of innumerable points in a plan view, a case where the adhesive is provided in a plan view mesh shape, a stripe shape, and the like.

Further, when a heat insulating film 32 (foamed resin film, nonwoven fabric, etc.) is directly laminated on the back surface of the cellophane layer 2 as shown in FIGS. 3, 4 and 6, as shown in FIG. 7 (a). The small holes 71 penetrating in the thickness direction of the cellophane layer 2 may be provided in the surface of the cellophane layer 2. In the illustrated example, the small hole 71 also penetrates the design print layer 5. But the small hole 71 does not need to penetrate the design printing layer 5. FIG. Further, as shown in FIG. 7B, small holes 72 penetrating in the thickness direction of the cellophane layer 2 and the synthetic resin film 31 may be provided in the plane of the cellophane layer 2. In the illustrated example, the small hole 72 also penetrates the design print layer 5 and the adhesive layer 61.
Note that the layer structure of the support film 3 in FIG. 7A is taken as an example of the layer structure in FIG. 4, and the layer structure of the support film 3 in FIG. 7B is taken as an example of the layer structure in FIG. Although it has taken, the layer structure of the support film 3 in the case of providing a small hole is not necessarily limited to this.

  Each of the small holes 71 and 72 is generally a hole having a substantially circular shape in a plan view, but is not limited thereto, and may be independently a substantially elliptical shape, a substantially rectangular shape, or a substantially star shape in a plan view. Good. The size of each small hole 71 and 72 is not particularly limited, but if it is too large, the appearance of the dew condensation suppression label 1 is deteriorated, and if it is too small, it may not function sufficiently as a moisture passage. From this point of view, the size of each small hole 71, 72 is preferably independently 0.05 mm to 1 mm in diameter and 0.1 mm to 0.5 mm in diameter on the basis of the small circular hole in plan view. Is more preferable. In addition, the size of each small hole 71 and 72 when each small hole 71 and 72 is not substantially circular shape in planar view shall be a circle equivalent diameter of the same area as each said small hole 71 and 72. As shown in FIG.

  By providing the small holes 71 and 72 in the cellophane layer 2, the moisture absorbed in the cellophane layer 2 can easily migrate to the heat insulating film 32 (foamed resin film, nonwoven fabric, etc.) through the small holes 71 and 72. In particular, the adhesive layer 61 that adheres the cellophane layer 2 and the heat insulating film 32 is provided in a non-solid form so as to have gaps 61a and 62a that do not have an adhesive in some places, as shown in FIG. Thus, moisture easily moves from the small holes 71 and 72 through the gaps 61a and 62a to air gaps such as air holes and interfiber gaps of the heat insulating film 32. Further, when the nonwoven fabric is composed of hydrophilic fibers such as natural fibers such as cellulose fibers and cotton, and / or is composed of synthetic fibers subjected to hydrophilic surface treatment, each small hole 71 , 72 is preferable because the moisture from the non-woven fabric is easily absorbed by the non-woven fabric, and the moisture is quickly transferred from the cellophane layer 2 to the non-woven fabric.

Further, the support film 3 may have heat shrinkability or a film that does not have heat shrinkability. Here, heat shrinkability refers to the property of shrinking in a predetermined direction when heated to a predetermined temperature (for example, 70 ° C. to 120 ° C.).
In the case of (1), such a support film 3 is a synthetic resin film having heat shrinkability, and in the case of (2), a heat insulating film having heat shrinkability is used. In the case of (3), a film in which at least one of the synthetic resin film and the heat insulating film has heat shrinkability is used.
The cellophane layer 2 usually does not have heat shrinkability, but the label base 4 having heat shrinkability can be constituted by laminating and bonding the support film 3 having heat shrinkability to the cellophane layer 2.

The label base material 4 having such heat shrinkability may be configured so as to mainly thermally shrink at least in the horizontal direction and thermally change in the vertical direction. In addition, the horizontal direction of the label base material 4 becomes a circumferential direction when it is mounted on an adherend such as a container.
The thermal contraction rate in the lateral direction (thermal contraction direction) of the label base material 4 is not particularly limited, but is preferably 10% or more, and more preferably 20% or more. In addition, although the heat shrinkage rate in the said horizontal direction is so preferable that it is large, since the cellophane layer 2 which is hard to heat-shrink is laminated | stacked, there is a limit naturally, for example, the heat | fever in the horizontal direction (heat-shrink direction) of the label base material 4 is. The shrinkage rate is 60% or less. When the label base material 4 is thermally changed in the vertical direction (thermal shrinkage or thermal extension), the thermal contraction rate in the vertical direction of the label base material 4 is, for example, -1% to 10%. In addition, the minus of thermal contraction rate means thermal expansion.
However, the heat shrinkage ratio is the length of the label base material before heating (original length) and the length of the label base material after immersion in 90 ° C. warm water for 10 seconds (length after immersion). Is obtained by substituting into the following equation.
Heat shrinkage rate (%) = [{(original length in horizontal or vertical direction) − (length after immersion in horizontal or vertical direction)} / (original length in horizontal or vertical direction) ] × 100.

The label substrate 4 is provided with a design printing layer 5 displaying a design. The design printing layer 5 can be formed by a conventionally known printing method using a conventionally known printing ink. The design represented by the design print layer 5 is not particularly limited, and is, for example, a desired character, symbol, or design.
The thickness of the design print layer 5 is not specifically limited, For example, it is 0.5 micrometer-7 micrometers, Preferably it is 0.5 micrometer-5 micrometers.
The design print layer 5 is formed on the front side of the support film 3, the back side of the support film 3, the front side and back side of the support film 3, the front side of the cellophane layer 2, the back side of the cellophane layer 2, or the cellophane layer 2. Provided on the front side and the back side.
From the viewpoint of preventing scratches and ensuring water absorption from the surface of the cellophane layer, it is preferable that the design print layer 5 is provided except for the surface side of the cellophane layer 2.

Moreover, the design printing layer 5 is provided so that the design can be visually recognized from the surface side.
In FIG. 2, the synthetic resin film 31 (support film 3) and the adhesive layer 61 are transparent, and the design printing layer 5 is provided on the back surface of the synthetic resin film 31 (support film 3). In the case of the layer structure as shown in FIG. 2, the design print layer 5 may be provided on the back surface of the cellophane layer 2 and / or the surface of the synthetic resin film 31, although not particularly illustrated.
In FIG. 5, the design print layer 5 is provided on the back surface of the cellophane layer 2. When the synthetic resin film 31 and the adhesive layer 61 are transparent as shown in FIG. 5, the back surface of the synthetic resin film 31 and / or the front surface of the synthetic resin film 31 are not particularly shown. The design printing layer 5 may be provided, and preferably, the design printing layer 5 is provided on the back surface of the synthetic resin film 31 (between the synthetic resin film 31 and the heat insulating film 32).
In the case of the layer structure as shown in FIGS. 3, 4, 6, and 7, the heat insulating film 32 is usually opaque, so that the design print layer 5 is formed on the back surface of the cellophane layer 2 as shown. Is preferably provided. In this case, the design print layer 5 may be provided on the surface of the heat insulating film 32 (not shown), but it is preferable to provide the design print layer 5 on the back surface of the cellophane layer 2 because the design print layer 5 can be formed cleanly.

The dew condensation suppression label 1 is used by being attached to an adherend.
The adherend is not particularly limited, but typically, a container filled with the contents can be used. The contents are not particularly limited, and examples include liquid foods such as beverages, gel foods such as jelly, solid foods such as granule seasonings, pharmaceuticals, etc. Containers filled with contents that are stored in a cold state. In addition, it is preferable to attach the dew condensation suppression label 1 of the present invention.
The container may be a relatively hard container such as a PET bottle, or may be a soft container such as a pouch container or a pillow bag container.
For example, FIG. 8 shows an example of a hard container.
As illustrated in FIG. 8, the container 9 includes a container main body 91 and a cap portion 92 that closes the spout of the container main body 91. The container main body 91 has a bottom portion serving as a self-supporting surface and forms a storage space for storing contents, a shoulder portion 912 formed above the body portion 911 and having a diameter reduced toward the top, The cap portion 92 is attached to the upper portion of the shoulder portion 912 so as to be opened and closed.

The outer shape of the body portion 911 of the container main body 91 is not particularly limited, and is substantially cylindrical as shown. Other shapes are not shown, but are substantially elliptical pillars, substantially square pillars, substantially hexagonal pillars, etc. Alternatively, a substantially polygonal frustum shape such as a substantially elliptic frustum shape or a substantially quadrangular frustum shape, a substantially daruma shape, a substantially saddle shape, or the like may be used.
In the present specification, the “substantially” shape means a shape allowed in the technical field to which the present invention belongs. The “substantially” such as the substantially cylindrical shape includes, for example, a shape in which a part of the circumference is slightly inflated or depressed, and a shape in which a part of the circumference is slightly straight or oblique. The “substantially” such as the substantially quadrangular prism shape includes, for example, a shape in which a corner is chamfered, a shape in which a part of a side is slightly inflated or depressed, and a shape in which a side is slightly curved.

The body portion 911 and the shoulder portion 912 of the container body 91 may have a generally smooth outer surface, but preferably, at least one of the body portion 911 and the shoulder portion 912 of the container body 91 is a recess 91a. More preferably, at least one of the trunk portion 911 and the shoulder portion 912 of the container body 91 has an outer surface in which a plurality of recesses 91a are formed in the circumferential direction. In addition, a smooth outer surface means an outer surface having substantially no significant unevenness.
In the illustrated example, the outer surface of the body portion 911 has a substantially cylindrical shape in which six concave portions 91a are formed at equal intervals in the circumferential direction, and the outer surface of the shoulder portion 912 has a substantially truncated cone shape having a smooth curved surface. . Of the outer surface of the body portion 911, the portions other than the concave portion 91a are convex portions 91b protruding outward. The concave portion 91a and the convex portion 91b are relative concepts.
The material of the container main body 91 and the cap part 92 is not particularly limited, and examples thereof include synthetic resin, glass, earthenware, and metal.

As shown in FIG. 9, the back surface of the first side end portion 4 a of the dew condensation suppression label 1 is attached to the outer surface of the container 9 using an adhesive (or adhesive), and the label is attached to the body portion 911 of the container 9. After winding around, it is formed in a cylindrical shape by adhering the back surface of the second side end portion 4b to the surface of the first side end portion 4a using an adhesive (or adhesive). The adhesive (or pressure-sensitive adhesive) is not shown.
The adhesive (or pressure-sensitive adhesive) may be provided in advance on at least the back surfaces of the first side end portion 4a and the second side end portion 4b of the dew condensation suppression label 1, or the dew condensation suppression label 1 is placed on the container 9. When affixing, you may provide at the predetermined location of the dew condensation suppression label 1 and / or the container 9. When the adhesive (or pressure-sensitive adhesive) is provided on the dew condensation suppression label 1 in advance, it is preferable to use a heat-sensitive adhesive (or heat-sensitive pressure-sensitive adhesive).
When the label base material 4 having heat shrinkability is used, the dew condensation suppression label 1 formed in a cylindrical shape around the container 9 may be heated and thermally contracted as necessary. The heating temperature in this case can be appropriately set, and is, for example, 70 ° C to 120 ° C, preferably 80 ° C to 110 ° C. The heating means is not particularly limited, and examples thereof include steam and hot air of about 100 ° C to 250 ° C.

Thus, the labeled container 10 with the dew condensation suppression label 1 attached is obtained around the container 9 (see FIGS. 10 and 11). The surface of the dew condensation suppression label 1 is outside the container 9, and therefore the surface of the dew condensation suppression label 1 constitutes the outermost surface of the labeled container 10.
Since the dew condensation suppression label 1 is mounted including the recess 91a of the container 9 as described above, the mounted dew condensation suppression label 1 is in close contact with the protrusion 91b of the container 9, but the recess 91a of the container 9 is attached. Is far from. Therefore, a gap X is formed between the dew condensation suppression label 1 and the recess 91 a of the container 9. Therefore, the dew condensation suppression label 1 is mounted with a gap X partially between the container 9 and the container 9. The gap X is formed corresponding to the recess 91a. In the container 9 having a plurality of recesses 91a, a plurality of gaps X are formed between the dew condensation suppression label 1 and the container 9. Yes.

When the labeled container 10 is cooled in a refrigerator or the like and taken out at room temperature, moisture adheres to the surface of the dew condensation suppression label 1 due to the temperature difference between the inside and outside of the labeled container 10. Since the surface of the label 1 has the surface of the cellophane layer 2, moisture can be taken into the cellophane layer 2 and water droplets can be prevented from accumulating on the surface of the dew condensation suppression label 1. The dew condensation suppression label 1 of the present invention can suppress dew condensation on the surface because moisture is quickly taken into the cellophane layer 2 even if moisture adheres to the surface of the label itself due to the low temperature state.
In particular, when the dew condensation suppression label 1 in which the small holes 71 and 72 are provided in the cellophane layer 2, moisture taken into the cellophane layer 2 moves to the heat insulating film 32 through the small holes 71 and 72. Therefore, more moisture is taken into the dew condensation suppression label 1 and water droplets hardly accumulate on the surface for a long time.

Moreover, since the support film 3 is laminated | stacked on the cellophane layer 2, even if the cellophane layer 2 absorbs water and expand | swells, a deformation | transformation of the label 1 can be suppressed.
Furthermore, when the support film 3 has the heat insulation film 32, the temperature of the contents is not easily transmitted to the dew condensation suppression label 1, and the dew condensation suppression label 1 including the recess 91a is attached and the dew condensation suppression label. 1 and the concave portion 91 a of the container 9, the temperature of the contents is not easily transmitted to the dew condensation suppression label 1. For this reason, after placing the labeled container 10 at room temperature, moisture adhesion to the surface of the dew condensation suppression label 1 can be delayed, and in synergy with the water absorption of the cellophane layer 2 and the like, Thus, it is possible to provide the labeled container 10 in which water drops do not easily accumulate.

The present invention is not limited to the first embodiment and can be variously modified.
Hereinafter, various other embodiments of the present invention will be described, but the description of the same configurations and effects as those of the first embodiment will be omitted (assuming that the description has been made), and the terms and symbols will be used as they are.

[Second Embodiment]
2nd Embodiment is related with the dew condensation suppression label used affixing on a to-be-adhered body.
The dew condensation suppression label 1 of the present embodiment has a sheet shape, and is used by being attached to an adherend via an adhesive layer (or an adhesive layer).
FIG. 12 is a plan view of the condensation suppression label of the second embodiment, and FIG. 13 is a cross-sectional view of the condensation suppression label cut in the lateral direction.
The dew condensation suppression label 1 of the second embodiment also has a label substrate 4 and a design print layer 5 as in the first embodiment.
13 has a support film 3 and a cellophane layer 2 laminated on the front surface side of the support film 3, and a design printing layer 5 is provided on the back surface of the cellophane layer 2. Although not particularly illustrated, the design print layer 5 may be provided on the surface of the support film 3 instead of the configuration in which the design print layer 5 is provided on the back surface of the cellophane layer 2. In addition, the label base material 4 of the present embodiment may be changed to various layer configurations shown in the first embodiment.
A pressure-sensitive adhesive layer 63 (or an adhesive layer) is provided on the back surface of the label substrate 4. As the pressure-sensitive adhesive layer 63 (or adhesive layer), a conventionally known pressure-sensitive adhesive (or adhesive) can be used. For example, a pressure-sensitive pressure-sensitive adhesive, a heat-sensitive pressure-sensitive adhesive (or heat-sensitive adhesive), or the like is used. be able to.
In the example shown in FIG. 12, the label base material 4 (condensation suppression label 1) is formed in a substantially elliptical shape in plan view, but is not limited thereto, and is substantially circular in plan view and substantially rectangular in plan view. Any other shape may be used.

The dew condensation suppression label 1 of this embodiment can obtain a labeled container (not shown) by sticking it on the outer surface of an adherend such as a container via an adhesive layer 63 (or adhesive). The dew condensation suppression label 1 of the present embodiment is also attached to the container with a part of the space between the dew condensation suppression label 1 and the container to constitute a labeled container having a space between the dew condensation suppression label 1 and the container. preferable.
Similarly to the first embodiment, the dew condensation suppression label 1 and the labeled container of the present embodiment also take moisture into the cellophane layer 2 even if moisture adheres to the surface of the dew condensation suppression label 1 due to the internal and external temperature differences. Condensation can be suppressed.
In addition, the dew condensation suppression label 1 of this embodiment can also be used as an in-mold label. The in-mold label is a label that is integrated into the container at the same time as the resin molding when the synthetic resin container is molded. When used as an in-mold label, the pressure-sensitive adhesive layer 63 (or adhesive layer) is replaced with an adhesive layer that can adhere to the molding resin.

[Third Embodiment]
In the said 1st Embodiment, it demonstrated that the label base material 4 which has heat-shrinkability can be comprised by carrying out the lamination | stacking adhesion | attachment of the support film 3 which has heat-shrink property to the cellophane layer 2. FIG.
However, since the cellophane layer 2 is difficult to shrink, the label base material 4 that shrinks greatly cannot usually be obtained.
In the present embodiment, the configuration of the label substrate 4 that can be relatively thermally contracted will be specifically described.

As one means, the label substrate 4 is formed by partially bonding the cellophane layer 2 to the support film 3.
For example, as shown in FIGS. 14 and 15, an adhesive layer 61 that bonds the support film 3 having the same shape and the same size and the cellophane layer 2 is formed in a band shape extending in the vertical direction, and the band shape is formed with a predetermined interval in the horizontal direction. By providing (providing in the shape of a stripe extending in the longitudinal direction), it is possible to configure the label base 4 in which the cellophane layer 2 is partially bonded to the support film 3.
In FIG. 14, for the sake of convenience, the area where the adhesive layer 61 is provided is shaded.
In this way, the dew condensation suppression label 1 in which the adhesive layer 61 is provided in a stripe shape has a plurality of band-like regions 69 in which the both are not adhered between the cellophane layer 2 and the support film 3 in the lateral direction. The non-adhesive belt-like region 69 and the belt-like adhesive layer 61 both extend in the vertical direction, and the non-adhesive belt-like region 69 and the belt-like adhesive layer 61 are alternately arranged in the horizontal direction.

  When such a dew condensation suppression label 1 is heated, the cellophane layer 2 is unlikely to thermally shrink, but the support film 3 corresponding to the non-adhesive strip-like region 69 undergoes large heat shrinkage, so that the cellophane layer 2 greatly heat shrinks as a whole. In this case, since the cellophane layer 2 corresponding to the non-adhesive strip-like region 69 swells outward, the dew condensation prevention label 1 having an outer shape in which a plurality of longitudinally extending wrinkles are formed in the horizontal direction is obtained after heat shrinking. It is done.

As another means, the label substrate 4 is formed by adhering the cellophane layer 2 having a smaller area than the support film 2 to the support film 3.
For example, as shown in FIGS. 16 and 17, the cellophane layer 2 having a smaller area than the support film 3 is laminated and bonded to the surface of the support film 3 via an adhesive layer 61. In the illustrated example, the adhesive layer 61 is provided in a solid shape, but may be provided in a stripe shape as described above. The cellophane layer 2 having a small area is preferably laminated except for the first side end 4a and the second side end 4b. In the illustrated example, the cellophane layer 2 is laminated at the lateral center of the support film 3. The area of the cellophane layer 2 is not particularly limited, but is preferably about 30% to 70% with respect to the surface area of the support film 3.

When such a dew condensation suppression label 1 is heated, the cellophane layer 2 is unlikely to thermally shrink, but the support film 3 in the portion where the cellophane layer 2 is not laminated is greatly heat-shrinked, so that the cellophane layer 2 is largely heat-shrinked as a whole. Further, when the adhesive layer 61 is provided in a solid shape, the portion where the cellophane layer 2 is laminated is smooth even after heat shrinkage.
In addition, although the layer structure of the support film 3 of FIG.15 and FIG.17 has taken the layer structure of FIG. 2 as an example, the layer structure of the support film 3 of 3rd Embodiment is not necessarily limited to this.

[Other Embodiments]
In the said 1st Embodiment, although the winding label was illustrated as a form of the dew condensation suppression label 1, and a 2nd embodiment illustrated the tack label and the in-mold label, the dew condensation suppression label 1 of this invention has various in addition to this. Can be used as a form of label. For example, the condensation suppression label 1 of the present invention may be used in the form of a heat-shrinkable cylindrical label (also referred to as a shrink tube) by forming it in a cylindrical shape before being attached to the adherend. . Moreover, you may use the dew condensation suppression label 1 in the form of a glue label.
Furthermore, in the said embodiment, although the container 10 with a label which attached the dew condensation suppression label 1 to the container 9 which has the recessed part 91a was illustrated, you may mount | wear with the dew condensation suppression label 1 to the container which does not have a recessed part, or The condensation suppression label 1 may be attached to the smooth outer surface of the container so as not to include the recess of the container having the recess.
